With what force does the water press on the pipe plug, if the height of the water column is 3m

With what force does the water press on the pipe plug, if the height of the water column is 3m, and the area of the plug is 20 cm2?

Initial data: h (height of the water column, which presses on the plug) = 3 m; S (pipe plug area) = 20 cm2 (20 * 10-4 m2).

Reference data: ρw (water density) = 1000 kg / m3; g (acceleration due to gravity) ≈ 10 m / s2.

The force with which the water presses on the pipe plug is determined from the equality: ρw * g * h = P = F / S, whence F = ρw * g * h * S.

Calculation: F = 1000 * 10 * 3 * 20 * 10-4 = 60 N.

Answer: Water presses on the pipe plug with a force of 60 N.
